Yesterday, a jury was shown a video recording of Dunstan's police interview, taken after his arrest in July 2011.

In the video, Dunstan admitted he drove his late co-accused Bryan Law to the Rockhampton airfield, opened a gate after a chain had been cut and took photos of him riding a red tricycle onto the civil aviation area before he allegedly chopped at a Tiger helicopter with a garden mattock.

Dunstan said Mr Law's act was symbolic and "spectacular" and he tried to assist however he could.
